Title: Process of preventing electrostatic charges on synthetic polymeric textile materials
IPC: D06M13/292
Filed: 1961-02-15
Abstract: Antistatic agents for synthetic polymeric textile materials comprise alkali metal, ammonium or monoamine salts of diesters of orthophosphoric acid derived from aliphatic alcohols containing 2-5 carbon atoms.  The amine salts may be those of dibutylamine, triethylamine, diethanolamine, butyldiethanolamine, methyldiethanolamine, triethanolamine or morpholine, e.g. the salts obtained by reacting orthophosphoric acid dibutyl ester with diethanolamine or triethylamine.ALSO:The formation of electro static charges on synthetic polymeric textile materials, e.g. polyacrylonitrile and polyamides, is prevented or inhibited by treating them with an aqueous solution of an alkali metal, ammonium or mono amine salt of a diester of ortho phosphoric acid derived from an aliphatic alcohol containing 2-5 carbon atoms.  The amine salts may be those of dibutylamine, triethylamine, diethanol amine, methyl diethanolamine, butyl diethanolamine, triethanolamine or morpholine. 0.01-1% of the salt based on the weight of the material treated may be applied.

Title: The production of acyl derivatives of germinal gland hormone preparations
IPC: C07J1/00
Filed: 1935-02-22
Abstract: Acyl derivatives of germinal gland hormone preparations of high physiological activity are prepared by subjecting to the action of acylating agents polycyclic alcohols of the cyclopentano-polyhydrophenanthrene series containing in their ring skeleton and directly attached to the carbon atoms thereof, two hydroxyl groups and also two or three hydrocarbon residues. The reaction may be stopped after the formation of monoesters, and the mono esters may if desired be converted into di-esters by further acylation.  As acylating agents there may be used either the acid anhydride, the acid chloride, or the acid itself, in the presence or absence of catalysts.  In an example, hexahydro-methyldiol of the formula C19H22O2 produced according to Specification 434,390 is treated with acetyl chloride in benzene solution in the presence of pyridine on the water bath.  The reaction product is treated with hydrochloric acid and extracted with ether to yield a resinous acylation product.  Samples have been furnished under Sect. 2(5) of (1) 17-methyl androstandiol benzoate prepared by the action of benzoyl chloride in pyridine solution on methyl androsterone obtained according to the description in respect of sample 3 of Specification 446,501; (2) 17 - methyl - dihydro - follicle hormone monobenzoyl ester prepared by the action of benzoyl chloride on 17-methyl dihydro-follicle hormone; (3) 17-methyl-androstendiol-3 - 17 mono acetate prepared by the action of acetic anhydride on the parent diol at 0 DEG  C.; (4) 3-acetyl-17-benzoyl-androstendiol-3: 17 prepared by the action of benzoyl chloride in pyridine solution on the corresponding 3-acetyl compound; (5) 3-acetyl-17-methyl-androstandiol-3: 17 prepared by the acetylation of the parent diol under the same conditions as used in the case of sample 3; (6) 17 - ethyl - trans androstandiol - 3 - 17 benzoate prepared by the action of benzoyl chloride in pyridine on the parent diol; (7) dibenzoyl-17-methyl-androstendiol-3: 17 prepared by the prolonged action of benzoyl chloride at elevated temperature on the parent diol.  The Specification as open to inspection under Sect. 91 comprises also the acylation of any polycyclic alcohols similarly constituted to the male sex hormone, together with the subject-matter of Specification 452,447.  This subject-matter does not appear in the Specification as accepted.

[Classes 38 (ii) and 38 (iv).] In an arrangement in which a load circuit 11 is supplied from an A.C. source 10 through a transformer 12 and grid-regulated valves 13, 14 the grid circuits are energized through a transformer 16 with the resultant of two voltage components, one leading the anode voltage and the other lagging the anode voltage, the latter component being caused to increase with load so as to cause a progressive decrease in the circuit applied to the load circuit as the load increases beyond a predetermined value. The leading component is derived from a transformer 21 the primary'of which is connected across the supply source 10 whilst the secondary is associated with a phase-shifting circuit 19, 20, 22. The lagging component is derived from the drop in a resistance 23 fed through a phaseshifting circuit 24, 25, 26 by a current transformer 27 on the primary side of the main transformer 12. In addition to regulating the output voltage of a rectifying arrangement as shown, the invention may be applied to regulating the voltage of an A.C. load circuit fed through reversely-connected valves.

[Class 125 (ii)] An apparatus for filling collapsable tubes with paste &c. comprises a filling spout 1 which enters the tube during the filling operation, a retracting mechanism operative during filling, and a paste portioning mechanism for feeding the spout. The spout 1 is rotatably connected to a pump housing 16 in which a sleeve 2 is rotatably mounted. A piston 3 is operated by a connecting rod 4 and a lever 5 in a shaft 6. The lever 5 carries a roller 30 which co-operates with a cam 7 on a shaft 8. Another cam 9 on the same shaft operates a lever 11 through a roller 33. The spout 1 is connected by a gear-wheel 24 to a rack 25 and is turned on its axis when the paste supply is finished. The pumping member 3 is synchronized with the retracting mechanism operated from the cam 9, roller 33, lever 11 &c., to create suction in the filling spout before the tube is completely retracted. The mouth of the filling tube is contracted on the exterior to allow for surplus paste which adheres thereto, and is also tapered in the interior.
